How much does it cost to replace a TXV?
The cost for replacing the TXV on your AC unit can range anywhere from $800 to $1200. The price for replacing your AC refrigerant filter drier is roughly the same, ranging between $700 to $900.
How long does a TXV last?
They should last for the life of the A/C system, which is generally 15-20 years for a high quality system. (Many people end up replacing their systems between 12 and 15 years due to efficiency issues or deferred maintenance causing damage to more easily damaged components, such as the compressor.)
What causes a TXV to fail?
Do TXVs Ever Fail They can fail internally but most often they fail because of a blocked inlet screen (if they have one), contaminants entering the valve, loss of charge from the power head, bulb location, and positioning issues and overheating of the valve.
What happens to the evaporator when TXV is restricted?
With the TXV restricted, the evaporator will become inactive and run high superheat. This will cause the compressor superheat to be high. The 100 percent saturated vapor point in the evaporator will climb up the evaporator coil causing high superheats.

What causes a compressor to run high with a restricted TXV?
High Superheats — High superheats also are caused by the evaporator and compressor being starved of refrigerant. With the TXV restricted, the evaporator will become inactive and run high superheat. This will cause the compressor superheat to be high.
What causes low pressure with a restricted TXV?
A small amount of refrigerant vaporizing will cause a lower pressure. High Superheats — High superheats also are caused by the evaporator and compressor being starved of refrigerant. With the TXV restricted, the evaporator will become inactive and run high superheat.
How much does it cost to replace A TXV valve?
The repairman check the unit inside and outside and came to the conclusion that the TXV valve outside needs replacing. My unit is still under warranty (10 year compressor/5 year parts), and the part will be without charge. However, the labor is quoted at $602.
How is a filter drier installed on A TXV line?
Also, he/she should install a filter drier on the freon line during the process. It is a filter installed on the freon line to remove contaminates and moisture.If the TXV is actully the problem, a possible cause is debris in the line from installation.The proper filter drier will filter out the contaminates too.
Why is the TXV on my heat pump stuck?
The TXV on my 2 year old lennox heat pump is stuck closed. causing the unit to frost up on one side. The unit is outside on the ground. The part itself is under warranty. How much should the labor cost and what does the labor involve. can they reuse the refrigerant that they pump out?
What happens if you have A TXV failure?
It is uncommon to have multiple TXV Failures. Because most refrigerants in modern Heat Pump and Air Conditioners use 410A, this uses a POE synthetic oil that is not compatible with the old R-22 systems that use a mineral oil base. Basically, the oil can separate, and lump into little globs of glue.
